If you are getting spark then it's eitehr out of time or not getting fuel. Check your compression and if they are on the low side, then you cam may be out of time. Your cranks sensor should be down by the oil pan there really should be an engine code given though if it won't run unless it's a primary ignition problem. Or also check to see if you fuel filter is plugged, especially with the cold weather, it could have ice in it prventing fuel from going to injectors.
